Anybody can make biodiesel. It's simple, you can make it in your kitchen area-- and it's BETTER than the petro-diesel fuel the big oil companies sell you. Your diesel motor will run much better and last longer on your home-made fuel, and it's much cleaner-- better for the environment and much better for health.

If you make it from used cooking oil it's not only inexpensive but you'll be recycling a bothersome waste product. Best of all is the GREAT feeling of freedom, independence and empowerment it will give you. Here's how to do it-- everything you need to understand.

Straight vegetable oil fuel (SVO) systems can be a clean, efficient and economical alternative. Unlike biodiesel, with SVO you have to modify the engine. The very best method is to fit a professional singletank SVO system with replacement injectors and glowplugs optimised for veg-oil, in addition to fuel heating.

With the German Elsbett single-tank SVO system for example you can use petro-diesel, biodiesel or SVO, in any mix. Just launch and go, stop and switch off, like any other vehicle. Journey to Forever's Toyota TownAce van utilizes an Elsbett single-tank system. More

There are likewise two-tank SVO systems which pre-heat the oil to make it thinner. You need to start the engine on normal petroleum diesel or biodiesel in one tank and then switch to SVO in the other tank when the veg-oil is hot enough, and change back to petro- or biodiesel before you stop the engine, or you'll coke up the injectors.

3. Biodiesel or SVO?

Biodiesel has some clear advantages over SVO: it operates in any diesel, without any conversion or adjustments to the engine or the fuel system-- just put it in and go. It also has better cold-weather residential or commercial properties than SVO (however not as excellent as petro-diesel-- see Using biodiesel in winter). Unlike SVO,

it's backed by many long-term tests in many nations, consisting of countless miles on the roadway.

Biodiesel is a clean, safe, ready-to-use, alternative fuel, whereas it's reasonable to state that many SVO systems are still speculative and further development.

On the other hand, biodiesel can be more costly, depending just how much you make, what you make it from and whether you're comparing it with brand-new oil or used oil (and depending on where you live). And unlike SVO, it needs to be processed initially.

But the big and rapidly growing worldwide band of homebrewers don't mind-- they make a supply weekly or as soon as a month and soon get used to it. Many have actually been doing it for several years.

Anyway you have to process SVO too, especially WVO (waste vegetable oil, utilized, cooked), which numerous individuals with SVO systems use since it's low-cost or totally free for the taking. With WVO food particles and pollutants and water must be eliminated, and it most likely must be deacidified too. Biodieselers say, "If I'm going to have to do all that I may too make biodiesel instead." But SVO types scoff at that-- it's much less processing than making biodiesel, they state. To each his own.
